I built a motorized bicycle about a week ago, but can't imagine touring with it. It would be fun, but I would want to carry plenty of spare parts! Only ridden it 50 miles so far, get about 150 mpg, but it is tempermental. I can just imagine breaking down 50 miles from a town in 120 degree heat and having to PEDAL the behemoth the rest of the way... It would be a fun adventure though. How does that Sachs motor hold up? I have a spitfire 48cc on a cruiser bike, does about 20-25 mph, and climbs most hills real well...
